Initial stages of failure of an orthogonally reinforced composite material

ML is the result of crack formation in the hybrid composite material.
The loss of continuity in uniaxial loading can be recorded both by the ML method and (in individual cases) by strain gauging.
For the hybrid composite in combined loading in the plane stress state, ML indicates (in contrast to strain gauging) the instant of the start of cracking.
